Water

Coastal bathing beach with a watershed of 619 hectares. The Quinquis watercourse is the nearest river to the bathing area.

Location

Plestin-les-Grèves commune, Lannion-Trégor Communauté, Brittany region, France.

Water Quality

Water quality has been classified according to both the 1976 and 2006 EU Bathing Water Directives. Bacteriological monitoring by the regional health authority (ARS) was conducted between 2012 and 2017, measuring E. coli and enterococci concentrations. The nearby recreational shellfish harvesting zone of Beg Douar experienced periodic closures due to water quality concerns. Ulva seaweed deposits were observed in the area between 2010 and 2015.

Risks

Potential pollution sources include wastewater collection and treatment systems, stormwater drainage systems, agricultural activity on the watershed, and a marine racecourse facility. The Quinquis watercourse carries bacterial contamination from agricultural activities in its watershed. Non-compliant individual wastewater treatment systems (ANC) exist on the bathing water's watershed.
